Basement waterproofing

Basement waterproofing is required when there is no efficient external drainage and/or there is no possibility to install additional waterproofing (no access from outside).

 

With no protection from the outside basement or cellar walls and floor may be affected by a high ground water table or rain water.

Sometimes hydrostatic pressure pushes the water through any cracks, broken or missing mortar, unsealed holes around incoming or outgoing services into walls and floors which then affect all internal finishes.

Some common issues include a broken, defective or blocked rainwater system including gutters and downpipes- large leaks may leak directly onto the structure (creating penetrating damp) or into the ground which then affects foundations, footings, slabs, floors and walls.

Rarely we may also suffer from old mining shafts, underground rivers or excavation works done to the neighbouring properties.

 

Internal damages and damp related issues are usually easy to spot while external damages to the existing structure can be easily missed which affects the whole condition on the property. Symptoms of water affecting the structure can be:

- cracks (both horizontal , vertical or diagonal on walls

- cracks around other structural elements- like lintels, steel structure, footings or foundations

- Wall deformations (bowing)

- efflorescence usually a whitish powdery residue- looking “salty” on the walls

 

Blue Magic Crystal Ltd recommends waterproofing all basements or cellars which have any signs of damp.  Our Crystal Injection © method can also be used as “vertical injections” this protects the whole wall from floor level to a required height. When this is done we install a waterproof render (1 x SIKA based render- 2 coats of tanking and second coat of SIKA based render).

When this is done the wall can be plastered with multi-finish or plasterboard can be installed (subject to site condition and thickness’ allowance)

For more details on this system please follow the link “vertical Crystal Injection”.

 

Blue Magic Crystal Ltd can also install cavity drainage membranes including basement and cellar sump pump systems.
