Impact of poor drainage on foundations
If water isn’t draining correctly from around the buildings, the foundations can be heavily impacted, requiring emergency drain repairs. Clay soil is notorious for having these types of problems where the soil expands and contracts seasonally, expanding in wet weather and contracting in dry weather. This expansion and contraction however, doesn’t act uniformly and it’s this imbalance that can lead to cracking foundations.
Soil can also be eroded by excessive runoff, reducing the stability of the soil and threatening the integrity of the foundations. Even something as simple as blocked guttering can overflow onto the ground and cause the foundations to move, as can blocked grated drains and pits that release waterflow onto the ground instead of into the stormwater drainage system.
Signs that the foundations are affected by poor drainage
Rising damp, crumbling plaster, peeling paint, rotting timber, cracking brickwork, sloping or sagging floors, jammed windows and doors, cracked cornices – these are all indications that there is movement in the foundations. The biggest cause of foundation problems is poor drainage, so it’s vital that drainage repairs and solutions are initiated immediately, before the situation worsens.
Rising Damp Solutions
Excessive water flow under foundations results in brickwork drawing water up into the walls that result in cracking or peeling paint, musty smells and mould which can lead to health problems. Adept can provide a variety of solutions to rectify rising damp.
Subfloor Ventilation
Cross flow ventilation is an important part of rectifying musty damp smells, mould and assisting in drying out subfloor areas in conjunction with Adept’s successful drainage solutions.
Why Resin Injection Won't Fix a Drainage Problem
Chemical injection was never designed for permanent foundation stabilisation, it was designed for temporary slab support only. There is NO substitute for concrete which is the ONLY way to guarantee your issues are resolved permanently the first time. Read Pro’s and Con’s
Example of failed resin injection procedure – correspondence with a client: I have subsidence in my foundations around where old clay pipes have been removed. I previously had resin injections completed but it has not addressed the issue and now the roof frame is damaged. I would like to obtain a more permanent solution.
