Why you should waterproof a concrete fire tank

One of the most important issues facing builders when constructing underground concrete water tanks is waterproofing.

Making sure there are no water leaks from the tank or water seepage from the surrounding soil is one of the biggest concerns for those building a concrete tank, because it has to resist the negative pressures that develop when the tank is emptied or filled, and combat the thrusts that come from the 'rising water table and the surrounding soil.

Fire protection systems, also known as active fire protection systems, consist of a set of components, including interior waterproofing with EDDM waterproof membranes Hidrostan.

By providing 'reserve water, fire reservoirs provide peace of mind and disaster protection, and in areas of the country where water use is restricted in drought conditions, water reserves can be used for lawn irrigation. A green lawn limits the risk of fire.

Providing durable waterproofing for a concrete fire pit is one of the most complex challenges in construction.

The use of Hidrostan® EPDM membranes is a highly effective and reliable solution to solve these critical issues. Due to their high flexibility and strength.


Hidrostan® membranes in EPDM are the ideal solution for rehabilitating old concrete, glass resin, and steel vessels that have leaks or cracks that are difficult to resolve, and can be lined with pre-welded, pre-formed or pre-shaped sheets or welded in place with cold solutions. Lining with Hidrostan® EPDM membranes allows for the provision of connections for drain or fill pipes. Their chemical-physical characteristics guarantee a perfect watertight seal, and the availability of the different thicknesses, 0.70 - 1.00 -1.20 - 1.50 - 2.00 mm, leaves a wide freedom of design choices. Hidrostan® EPDM membranes are certified for both wastewater and drinking water.
