Why Drainage Repair Starts Underground

  • Drainage Repair

When dealing with drainage problems, it is tempting to try to fix surface-level symptoms like pooling water, soggy grass, or cracks in your foundation. However, lasting drainage repair requires digging deeper. The soil on which your property is located plays a significant role in how water flows, settles, and drains. Without a clear understanding of what you’re working with, even the best-laid repair plan is destined to fail.

Not All Soils Are Equal

Different locations in Surrey are home to various types of soil. Some houses stand upon clay, some on sandy, and some upon loamy soils. These diverse soils absorb and pass water in very different ways. Clay soils absorb water and drain slowly. Sandy soils drain water fast, with a risk of erosion. Loam, being a blend of sand, silt, and clay, drains well and retains nutrients but demands quality grading. This variety between neighbourhoods is the reason the same solution will not work everywhere. With drainage repair, Surrey properties require a tailored approach, as a repair technique that works well in one location may not be suitable in another.

How Soils Influence Drainage

Soil does not just affect water absorption, but also determines how deep to dig, what materials to use, and where to install a pipe. With clay, for example, it’s crucial to make sure water is not close to the surface. If it is, water can seep into basements, cause foundation problems, or damage trees and grass.

On the other hand, when dealing with sandy soils, water drainage needs to be slowed down so the soil remains moist and dry spots do not develop. Without these additional steps for drainage repair, Surrey properties may continue to face the same recurring problems.

Soil Assessments

All drainage jobs in Surrey should begin with a soil test. This could be as simple as conducting a field test, such as digging a trial pit to see how well it drains. By doing this at the onset of a draining repair, we can better understand what’s happening below the surface, allowing us to design a tailored solution that considers the water movement on your property. Without this step, the short-term solutions may not survive the following season. Taking the time to understand the soil type ensures a solution that is both long-lasting and effective.

Drainage Systems

Fixing an area of pooling water is not all there is to drainage repair. Technicians need to ensure the entire system is working as a unit, including grading and soil, downspouts and trench lines. Beginning with soil is critical because it provides the overview to create a system that is a proper match for your home, yard, and climate.

Sometimes, Surrey homeowners attempt to perform drainage repairs themselves or hire contractors at a discount who fail to conduct a thorough soil assessment. These property owners end up paying extra to correct or redo work that was not suited for the soil on their land. The best place to begin is with a solid foundation.

The Importance of Soil

Understanding the soil type on a property is crucial for effective drainage repair. Technicians work best if this first step is done right. This process helps us prevent mistakes, plan more efficiently, and provide the results that leave your property dry and safe in the long term. At West Coast Drainage, we begin with the ground itself. By letting the soil guide our repair, we tailor solutions to your property and not the other way around.
