Why is choosing a manhole reinstatement that is BBA/HAPAS approved so important?

When reinstating manholes choosing products with a completely independent third party approval can offer the client total confidence and peace of mind, that the system they are using is proven to provide high performance and quality.

There is the added bonus of no split liability with the anticipated service life of 5 years.

Can a polyester resin bedding mortar be used in wet weather?

Effectively – no – as water interferes with the curing process in polyester resin systems. The perfect alternative would be to use UltraCrete Envirobed HA104®, which has the same attributes as a resin alternative, but additionally, has consistent performance in wet conditions.

When can UltraCrete mortars receive traffic?

All UltraCrete fast set bedding mortars can be trafficked within an hour, with the exception of UltraCrete M90 (which can be trafficked in just 2 hours). All UltraCrete bedding mortars will set in approx. 15-20 minutes, dependent on temperature.

What are the minimum and maximum application depths for UltraCrete bedding mortars?

On average, UltraCrete bedding mortars can be used for depths between 10-50mm, with the exception of UltraCrete M60, which has a maximum depth of 75mm, and UltraCrete PY4/5 which has a maximum depth of 5mm.

What is the difference between UltraCrete QC10 and UltraCrete Post Fix?

Both UltraCrete QC10 and UltraCrete Post Fix are rapid strength concretes. UltraCrete QC10 has a much higher strength gain than UltraCrete Post Fix, so is more suitable for back-filling around ironwork as part of the BBA/HAPAS Approved Ironwork Reinstatement System. It is also effective when erecting heavyweight fencing and signs, whereby the post/sign can be erected in one application instead of waiting for the more conventional concrete to gain strength.

Why do the UltraCrete SCJ cans sometimes become blocked?

If an UltraCrete SCJ can has become blocked it is highly likely that the nozzle has not been cleaned after use. We recommend after each spray, that the can is held upright and sprayed for a few seconds in order to clear the nozzle. This will avoid any blockages and prevent waste.

Is UltraCrete Instant Road Repair® suitable for temporary reinstatements?

UltraCrete Instant Road Repair cold lay asphalt concrete can be used for temporary reinstatements but also as a first time permanent reinstatement on type 2, 3 and 4 carriageways, footways and cycle tracks.
