Refurbishment of existing rainwater drainage systems

As rainfall intensities increase, many buildings are finding that the level of rainfall protection they currently experience is insufficient.

Usually this is because either modern day rainfall intensities exceed the designed level of protection or that the level of protection was under designed in relation to the building use.  


Clearflow Products ltd offer an onsite consultancy, where the existing system failure can be identified and a corrective plan put into place to upgrade / maintain the existing systems.

This gives peace of mind that the integrity of the building will be maintained.

Every refurbishment project has its own special requirements examples such as carrying out installation in live working environments, areas congested with services, poor access / egress or inadequate underground drainage.


All these are day to day matters which can be simply resolved by consultation with the right people.
