Basement Waterproofing



If you have a basement, cellar or other room which is below ground level or where external ground levels are next to internal floor levels it will require waterproofing to prevent water from entering your home. With the right scheme it can be converted to a dry, habitable room by the installation of a suitable waterproofing system.

Structural waterproofing is a highly specialised operation, using various types of materials and techniques appropriate to the nature of the building and clients requirements.  Our Surveyor will inspect the basement/cellar and discuss with you how you want to use the space to ascertain the level of waterproofing recommended.




Penetrating damp is caused by water leaking through masonry and walls due to structural problems in a building i.e. faulty or blocked guttering and drainpipes, cracked or missing roof tiles or damaged joints and missing pointing.  Water will usually travel in a horizontal movement across walls and ceilings (unlike Rising Damp which normally travels up walls) leaving discolouration and peeling/flaking of paintwork and wallpaper.

Seaside properties and those in exposed areas can also be affected by penetrating damp due to wind driven rain causing damp patches to appear on walls and ceilings which will get darker when raining

It is more likely to occur in older buildings with solid walls and no cavity but can also be as a result of internal leaks in newer properties.




Structural timber beams can become weakened by wet and dry rot attack and also by wood boring insect attack.  In some cases it may be that the end beams have become too weakened and the bearing has become insufficient.

There are different methods of repairing including a Flitch Beam repair which involves cutting a slot, or slots, along the length to within about 30-40mm of the base and bonding in a High Tensile Reinforcing bar with Structural Epoxy Pouring Grout. This is known as a ‘modified flitch’ design and approximately doubles the bending stiffness of a typical timber. It is also possible to use steel flitch beams in stead of grout.

We can also extend rotten or decayed joist ends and other structural timbers .
