Combo Roof Waterproofing System

Combo Roof system is a comprehensive system comprising of waterproofing, thermal insulation and finishing for the roof. This unique system is a technically advanced fast curing. Dubai Central Laboratory (DCL) Certified PU Foam system which forms joint free water proofing and thermal insulation is fully bonded to the roof slab. This system provides a manufacturer’s Guarantee of 25 years against any leakage.The system meets all latest thermal insulation standards and regulations in UAE and is accepted by all major property developers, consultants and contractors. The system is also approved by various authorities like Dubai Municipality, Sharjah Municipality, Sharjah Water and Electricity authority and Trakhees.

Septic Tank

Septic Tanks are design with two chambers giving primary settlement of sewage and allowing secondary settlement before discharge of the effluent. They can also be fitted with a filter to prevent small solids from blocking the soakaway .


Septic Tank Soakaway Systems, Problems and Drainage Fields - How they work

A septic tank soakaway system performs two functions:-
1/It uses naturally occurring aerobic soil bacteria to further clean the pollutants in the effluent
2/It disperses septic effluent into the soil,

Three mandatory tests required to install a septic tank soakaway. If you can't have a soakaway, you can't have a septic tank and must consider using a sewage treatment plant instead.

The 3 tests are:
The site must not be in an Environment Agency Groundwater Source Protection Zone. This is to protect abstracted drinking water
The site must pass the deep Trial Site Assessment Hole Test and never have either groundwater (the water table) or rock within 1 metre of the soakaway drain pipe
The site must consist of soil that passes the Percolation Tests - not too sandy or heavy.

Expansion joint

What is an expansion joint?

In building construction, an expansion joint is a mid-structure separation designed to relieve stress on building materials caused by building movement induced by:

- thermal expansion and contraction caused by temperature changes,
- sway caused by wind,
- seismic events, etc.
Because the joint bisects the entire structure, it marks a gap through all building assemblies--walls, floors, roofs, decks, planters, plazas, etc.  This gap must be filled to restore the waterproofing, fire proofing, sound proofing, air barrier, roof membrane, trafficable surface and other functions of the building elements it bisects.
Expansion joint systems are used to bridge the gap and restore building assembly functions while accommodating expected movements.
The term "movement joint" has been widely adopted in preference to "expansion joint" as it more appropriately encompasses the fact that building movement results in both compression and expansion of the material installed.
For example, when a structure heats up, the building materials from which it is built expand.  This causes the "expansion joint" to close down, thereby compressing the expansion joint system installed in the gap. 
Conversely, when the temperature drops, the materials cool causing the joint gap to open.  This requires the expansion joint material to expand to follow the joint movement.
