Introduction
Mr G of New Milton, contacted Prokil to inspect his communal basement garage situated underneath three houses that had an issue with water penetration which was running under the footprint of the three houses.
Basement Survey Findings
Jason Syrett, our Certificated Surveyor in Structural Waterproofing (CSSW) visited the property to commence the full investigation of the external communal basement garage. The area surveyed was a partially below ground garage. Jason noted the presence of two sump and pump chambers, one at the front and one at the rear of the garage to deal with excess water drainage.
Following the basement waterproofing inspection Jason submitted his full report to Mr G, complete with recommendations on the best basement waterproof system to restrict future water penetration. The report recommended that the BS8102 code of practise be followed which stipulates that a garage, forming “grade 2” accommodation, should incorporate a full waterproofing system where no water penetration is acceptable but some seepage is.
Mr G requested the installation of a partial cementitious tanking (Type A) basement waterproofing system and accepted the potential of water seepage on walls and junctions not covered by a full basement waterproofing system.
The report included a detailed breakdown of the costs to install the partial basement waterproofing system as requested.
Getting to Work
Step 1
Preparation of walls ready for the installation of a Type A waterproofing barrier protection to the front and rear walls of the garage.
Step 2
Render coats applied to the front and rear walls of the garage.
Step 3
Finally the walls were coated with two coats of Vandex BB75 a cementitious waterproofing render.
The Finished Result
After installing the partial cementitious tanking (Type A) basement waterproofing system and plastering, the area was left clean and tidy and ready to be used by Mr G.
It was also recommended that if over painting is planned that only trade matt water based vapour permeable paint should be used.
