Common causes of concrete damage and defects
Build quality (poor batching or compaction of concrete, insufficient concrete cover of steel reinforcement)
Mechanical (impact –vibration –explosion)
Chemical (alkali aggregate reaction –chemical attack bacterial action)
Crystallization with improve elasticity
especially designed to be comes an integral part
of the concrete
Non- toxic – microbiological growth.

Basements are prone to water leakages and water flooding and hence basements need a quality basement waterproofing. Some might ignore the basement leakages problems and some totally shut down the basements due to prolong water leakage problems in basements. But you should not underestimate the importance and usages of basements. Though, it is advisable to have a full-proof basement waterproofing while construction the buildings, but even if there is basement waterproofing failure happen, it can be treated with right treatments, quality products and proper workmanship.
Treatments should be recommended based on the problems. It is very important to identify the water sources and to understand the causes of basement leakages.
