How to Chemical Injection Roof Waterproofing – Understand

Must read

There are some common problems in terms of roof waterproofing failures in reinforced concrete structures. They are the appearance of cracks, openings and fissures that allow water percolation.

In general, roof insulation that present this type of seepage failure require waterproofing specialist  it also needs special attention and replacement of the asphalt blanket.

A modern technique that promises the roof leakage waterproofing is chemical injection to seal the openings. This process is injection roof leakage treatment.

It is necessary, however, to understand in greater depth to avoid warehouse waterproofing problems in the future.

What is chemical injection roof waterproofing?

Roof waterproofing in Pakistan, as we already know, is a fundamental and indispensable step during the construction phase. It provides the structural elements of reinforced concrete with protection against the attack of moisture and water infiltration.

Exposed slabs such as roofs, marquees, playgrounds, balconies, garages, mezzanines and the like need roof waterproofing services DHA.

The conventional methodology throughout the country is waterproofing with asphalt blanket offered by We apply the blanket directly to the substrate free of impurities and later cover with subfloor.

This technique consists of identifying the openings and fissures through where water is percolating and causing infiltration. In this case we inject the waterproofing chemical in Lahore in order to seal and close these points.

The injection waterproofing chemicals vary according to the type of use. In general, they are two-component polyurethane (PU), acrylic or vinyl gel.

We apply the injection under pressure and is capable of sealing capillaries with minimum thickness.

The waterproofing services in Lahore with chemical injection permanently seals fault sites. So, they won’t have any more problems.
