Arti Structural Waterproofing Ltd |
Delta Registered Installers, Arti Structural Waterproofing Ltd, provided a Type C waterproofing solution for a private dwelling. The project was installed quickly, on time and on budget.
The scope of the project was to provide a structural waterproofing solution to a private dwelling with a new-build extension. The property, situated on a sloping site, gave the opportunity for the waterproof design to utilise the property's environment to allow for natural discharge of any potential water ingress.
The property was detached and has front and side elevations with ground sloping down and away to a small stream. The retaining walls on either elevation rise at their highest point to approximately 1500mm above the internal floor level.
The internal walls of the property were original brick to the front and new cavity built concrete block. The floor of what was the original house is of solid concrete construction joining on to a newer block and beam floor construction.
Site inspections were carried out and Arti’s CSSW surveyor and Delta’s Technical Team discussed the design to ensure the waterproofing design would meet the client's requirements, and also meet BS 8102:2009 (the code of practice for protection of below ground structures against water from the ground).
Since the site was sloping, to achieve a level floor the new-build extension had to be recessed into the slope, which made the structure part retaining. Therefore, only part of the new-build required protection for water ingress. WDS, CSSW and CSRT qualified Stuart Tansey worked with Delta’s Technical Team to create specification suitable for the build.
No geology reports or soil analysis were available, therefore the recommendations and resultant specification were based upon a high-risk assessment during the initial site visit. Slight moisture ingress had been noted within the newly formed stairwell area, but the area had no recorded history of flooding.
Arti put together a cost-effective and compliant cavity membrane solution that utilised natural drainage to manage any potential water ingress.
This project is only part retaining as it is situated on a sloping site with an external ground level barely 1m tall at its highest point. Installing a waterproof membrane floor to ceiling was simply not required as water will never reach the highest points of the structure.
Before the installation of the Type C cavity drainage system, Arti ensured the waterproofing design would easily be maintainable and repairable.
With the installation complete in just three days and on budget, the homeowners were delighted.
The client said: "I just wanted to inform you that from initial meeting with Stuart Tansey on site, to completion of the project, the whole process was conducted promptly and with complete professionalism. This service was complemented by the managing director Mr Lucian Ardeleanu become personally involved providing his assistance and expert input with additional work I wanted carried out.
I would not hesitate to use their services again and would recommend Arti Waterproofing in future."
