Clay soil can make lawn care and gardening absolute hell.

If you need your clay based soil treated for planting grass whether in a
new yard or an old yard, We can turn that hard, lumpy concrete like soil into a softer loam using our state-of-the-art clay soil treatment.

First a quick explanation if what clay is and why it is such a problem for lawns and gardens read the information below.

The bottom line is that here in Alberta we are stuck with clay soils due to our geologic past. Much of south and central Alberta is an ancient sea bed.

The sea floor was made up of fine silt, sediments and of course a lot of sea salt. Over time this dried up sea floor sediment became clay. Clay is made up
from super fine particles of silt that are formed like platelets
(tiny smooth disk shaped pieces of aluminum silicate)
this fine material is ideal for making a concrete like soil matrix.

These microscopic platelets are held together with an electrical charge from the highly charged sodium chloride ions in the salt. The fine particles are held together tightly by this charge and when water is added it increases the binding effect.
The water is held in a tight layer between the platelets and act as a lubricant
which make it both slimy slick and sticky at the same time.

In order to make the clay less sticky when wet and hard as concrete when dry,
the electrical structure within the clay must be altered before it will loosen up
it's binding action.

There are many factors at play here, but in order to simplify the explanation, we'll focus on the salt in the soil. The salt (sodium chloride) must be broken down and the electrical charge dispersed before the clay can loosen. Our Clay Doctor process involves the use of a very strongly charged chemical ion compound dissolved in water. This compound has the exact opposite electrical charge as the sodium compound holding the clay together.

The strongly charged ion is introduced into the soil in a solution that immediately attacks the sodium molecules and break it apart. This action causes the clay platelets to relax or fall away from each other.

Many elements and molecules, including fertilizer components like NH4, K+, Ca++ and Mg++ are readily bound to the clay platelet. This makes them unavailable to plants. The molecules are held to the platelet by forces weaker than forces associated with ionization.

After the clay modification process is complete, both air and water can penetrate the soil. Soil Nutrients and minerals become more "bioavailable" so the plants can use them and thrive.

Also ideal for problem drainage areas, septic fields and areas prone to flooding
due to poor drainage. This stuff will fix your ailing septic field as well.


Clay Doctor Soil Modifier - Cutting Edge Soil Science

This process requires specialized knowledge and costly, complex application equipment, it is NOT a product in a bag or bottle a homeowner can apply themselves.

We can do treatments to residential lawns & gardens, commercial lawns, parks and rec areas as well as specialized sports playing fields and golf courses. In some cases we can also do agricultural plots, orchards and pastures.

Commercial lawns and Parks often have degraded lawns due to soil compaction, this is a huge problem when clay soils are used for the substrate of these lawns. After years of people walking on these lawns the soil becomes compacted to consistency of concrete. Once this happens, the grass will no longer thrive and go rapidly into decline. The water holding capacity of this soil is extremely poor, with most rainfall and irrigation simply running off. When hot weather hits, the soil dries out within a day or so and the lawn goes dormant. After treatment with soil modifier, the compaction is almost instantly relieved and the absorption potential of the soil increases to the point where it can hold onto moisture for weeks instead of days.

Due to its composition, Our liquid Clay Doctor Soil Treatment possesses an immense potential for an ion exchange (ionization). Small amounts of Liquid Clay Doctor Soil Modifier, when mixed with water, activates water molecules to H+, OH-, and H30+ ions, causing the water to become a highly ionized solution.

The result creates a vigorous exchange of electrical charges in the soil/clay particles, effectively neutralizing the ability of the platelet to attract and bind water, elements, and molecules. The clay soils then behave more like a loamy soil after the treatment.

There are many forms of treatments for clay like gypsum and calcium compounds, the problem is that these compounds are often not very water soluble and require "geological time" to work, meaning many years of application and a lot of patience. Clay Doctor Soil Modifier works within days and to a greater depth without mechanical mixing/tilling into the soil required by dry compounds.


The ion exchange occurs immediately and is carried into the soil as deep as the water penetrates. Soil conditioning utilizing the injection method of application will enable a deeper penetration of the product into the soil. The resulting soil conditions accelerate the natural aerobic bacterial growth and allow natural soil conditions to take place rapidly and more efficiently than before treatment.

The structure of heavy clay soils will improve and promote granulation. Soil drainage increases, enabling plant roots to grow more extensively, increasing the decomposition of organic matter, decreasing particulate water retention, and encouraging desirable micro-organisms while suppressing harmful soil bacteria.

Aerobic organisms encouraged in treated soils often become a natural defense against infection and disease. More elements and minerals will be made available, which results in improved, stronger plant growth.

Clay Soil & Dew Worms - A marriage made in hell !

Is your lawn covered in hard lumps of clay for dew worms ?

If so we can fix that.....

The ugly lumps on your lawn are caused when dew worms surface at night and deposit casting made up from clay particles ingested for under the surface of your lawn.

Dew worms rise to the surface when the soil is saturated and the nights are warm. They will also venture to the surface to feed on the lawns thatch layer if the soil is low in organic material they ingest for food.

After a rainfall or lawn watering, dew worms excrete small, uneven mounds of clay that can make lawns unsafe to walk upon and more difficult to mow. These lumps solidify in the dry air and form hard nodules that do not break down easily.

So, the worms are not really the problem. trying to kill them is not that answer. The worms are just doing what they do best, aerating the law's soil and increasing the fertility by carrying vital organic material deep into the soil layer under the lawn.

Worm castings full of clay make bumpy lawns

When your lawn has this many lumps and bumps, it requires drastic action.


A single application of Clay Doctor Soil Modifier can completely breakdown these lumps into a loose particles that reabsorb quickly into the lawns surface.

It also fixes the soil UNDERNEATH the lawn as well to prevent future clay lumps from reappearing later.

The process involves the application of the Clay Soil Modifier product by specially trained staff using injection, boom sprays, irrigation equipment, sprinklers, or similar methods.

The Clay Soil modifier, when applied via the injection process, is effective for deep soil conditioning needs related to bioswales and construction sites.

The Clay Soil Modifier may also be sprayed on soil, lawns, trees, shrubs, or flower beds and will not harm or burn living plants or organics found at surface level.

The Soil Conditioning Process requires water to be active and permeate the soil.

Its reaction with the soil is downwards following water channels deep into the soil with very little lateral movement.

Therefore, it is important to saturate the soil to the depth required to be treated. We use specialized equipment to facilitate this process, it is NOT a do it yourself product.

We do offer other solutions for clay soil treatment such as liquid Gypsum and Terrform soil conditioner. These products are effective but not as effective in single rapid treatment as Clay Doctor Soil Modifier.


The real problem is the clay lumps, not the worms

Does it not make sense to find a way to deal with the lumps !.

To hear the passion with which people seek a "control" for earthworms you could believe that worms are the worst pests on earth (or more appropriately, in earth). Of course, earthworms are beneficial and valuable to the overall health and tilth of the lawn. Their activity improves the growing environment by increasing air and water movement.

The presence of earthworms in the lawn is an indicator of healthy or reasonably healthy soil, it is when they make their presence known that they become a problem. Most of the time worms are unseen, conditioning the soil and living their lives deep in the root zone.

During the spring and fall, or other periods of extreme moisture, earthworms tend to migrate to the surface and leave their castings on the lawn. Worm castings are small mounds or bumps on the lawn which are basically worm excrement. The excretions are nutrient packed remains of digested plant matter and soil which is extremely beneficial to the lawn. The problem in some areas is that the castings also contain clay, which turn hard when dry.

Earthworms help in breaking down thatch, increasing decomposition and creating usable nitrogen in the soil. In fact, five or more earthworms per square foot of soil provides the lawn with 25% of its seasonal nitrogen requirements. The worms' movement through the soil profile acts as natural aeration, helping air and water move from the surface throughout the root zone.

Clay Doctor soil Modifier can be used to treat these lumps and break them down to a finer grained loam like texture easily absorbed back into the lawn.

A full soil modification treatment on a lawn will result in breaking down the surface lumps but it also goes deep into the lawn to treat the soil deep down so that in the future when the worms return to the surface, the lumps are no longer clay and breakdown quickly after watering or rainfall.

We have other compounds such as our Liquid Gypsum and Terraform Soil Treatment that can be applied by the homeowner when and if required to insure with any new lumps the soil
stays soft and friable (softer and loose).

After a clay soil modification treatment has been done, there are many other benefits beside getting rid of the lumps. The lawn now has soil that water can penetrate deep into during rainfall and watering. The lawns roots grow deeper providing a stronger turf.

The soil is once again allowing air and moisture to remain for longer which aids the beneficial soil microbes to thrive.

Your lawn will stay greener, maintain it's lushness longer and require less water and fertilizer than it did before the treatment.

early spring, June and late fall are ideal times for a treatment.
There are advantages to doing the treatment when the soil is very moist or wet as the process penetrates deeper. However we can do this process at any time during the summer, spring and fall.
