This new build house was having a problem with high water table in surrounding area.
The installation of 80mm land drains have been used, flowing into their own sump station before water enters the main sewer to catch any un-wanted sediment and silt.
We then ran a drainage pipe along the highest point across the side of the house, and then filled a trench with 10mm pea gravel to help water drain away. The 80mm drainage pipe has perforations so water can enter and flow along this to the sump station.
Another pipe then goes through the foundations and into the front of the house where water has been collecting, and is also buried in 10mm pea gravel. This takes away any water getting past the first pipe.
After installation we waited a week for rain to fall and checked for water under the floors, there was none indicating this method was a logical and the most cost efficient way to solve the water level problem.
The customer very happy, as a specialist damp proofing firm quoted around £6500 more than we did the job for.
This land drain project took 5 days to complete for 2 men and was completed in May 2015.
