Country House cellar

Flooded Country House Cellar


MACLENNAN-LSE were contracted by R.Moulding and Co of South Newton Salisbury to carry out waterproofing to a basement that flooded so quickly and to such a depth that the water flooded out through the basement door into the road outside. The contractor had 11,000 gallons of water removed one afternoon but the basement flooded and filled again the same evening.

MACLENNAN-LSE devised a flood water removal scheme and calculated the size of the pumps that would be required to remove the water from the cellar quicker than it came in.

MACLENNAN-LSE installed MACLENNAN perimeter drainage and Sumps and pumps. The wall membrane was Cellar-Tech system 500. The pumps were 4 individually piped NP400 pumps in two Newton Titan sumps.

The pumps are guaranteed for 3 years by MACLENNAN-LSE Membranes.


The walls were lined with an independent dry lining system with close cell insulation in between the and uprights. All services were installed behind the lining. The finished job was plaster boarded and finished with Thistle Multifinish.

All of the work was guaranteed by MACLENNAN-LSE for a period of 10 years. The pumps are checked and serviced every year by an independent pump servicing company.
