Porofoam is a range of low density foam concrete designed specifically for voidfill, stabilisation and other lightweight applications.
Foamed concrete is a highly workable, low density material incorporating up to 80% air. It is generally self levelling, self compacting and may
be pumped. Risk of plastic shrinkage or settlement cracking is significantly lower than that of standard concrete.
Porofoam is manufactured using CEMEX admixtures and is available in a wide range of densities and compressive strengths to suit your application and requirements. The product is easily placed with no compaction required and can be produced onsite by our foam generation units or delivered in trucks premixed.
Foamed concrete is ideal for filling voids
such as disused fuel tanks, sewer systems,
pipelines and culverts – particularly where
access is difficult. It is a recognised medium
for the reinstatement of road trenches. Applications include:
VOIDFILL - A low density flowable fill material to provide
a single, engineered solution. The material
has guaranteed performance in terms of
density, strength, or both. Therefore the
density and the strength of the construction
layer can be controlled over a greater
depth in a one-hit solution compared
to traditional fill materials.
ROADFILL - An efficient and cost-effective reinstatement
material that complies with the Roads and
Streets Works Act 1991. Porofoam Roadfill
is available as FCR Classes C2 and C4.
There is no settlement with Porofoam so therefore it can be fully resurfaced in one
operation. There is also no need for
TANKFILL - The more cohesive property of Porofoam Tankfill allows a controlled discharge into tanks with a restricted entry point. Air and gases in the tank are gradually displaced by the foamed concrete . Being a cellular fill, Porofoam is less prone to penetration from external contaminants. Porofoam Tankfill meets the building regulation codes for fire resistance. Applications:
Porofoam can be tailored to your requirements, our technical team will create a suitable mix design for your application. Porofoam can achieve strengths of up to 20 N/mm2 and our unique production process allows us to produce an extremely wide range of dry densities from as low as 300kg/m3 up to 2000kg/m3. For strengths and densities outside of this range our team will work with you to provide a solution.
Porofoam can be pumped, horizontally, vertically, or directly placed in layers of up to 1m single lift depth in order to maintain the required air void structure. The fluid nature of Porofoam allows the concrete to free flow into even the smallest of spaces making it highly suitable for voidfill applications. Porofoam can be pumped by either a conventional concrete pump or rotor stator pump. The material typically remains fluid for 2/3 hours after mixing with the foam (dependent upon ambient conditions). Porofoam also exhibits no settlement characteristics that may occur with granular fill materials allowing a much more stable fill.
Porofoam foamed concrete can be supplied
with or without coarse aggregate depending
on the type and application. The stable bubble
structure can be introduced into the mix in
Plastic state advantages
Foamed concrete is a versatile and practical material which can be tailored to a variety of project needs and operational conditions:
