Did you know: Using materials with high mass can add additional weight to an area that is already suffering from subsidence?
If you choose Polyurethane resins it means you can get the same result as concrete or aggregate without the risk of weight impact.
Polyurethane resins are light weight but also very strong. High strength and light weight means no risk of causing the compounding effect you could get from the additional mass of concrete and other heavier fills.
Because resin injection is much faster it means you won’t get held up waiting.
When installing piles and shoring on building sites for shoring there are often gaps between the piles allowing water and sand or earth to flow between the piles.
Using our quick setting resin injection foam we can inject between the piles, both closing the gaps between the piles and filling the ground behind the piles with stuctural grade foam.
When culverts are constructed they are backfilled and often have roads built over them. Due to water being directed to a culvert they can be susceptible to washout and subsidence of the road or structure above.
Using resin foam injection we can quickly fill the voids around culverts and stop subsidence and washout of backfill quickly.
When roads are built, the earth is reshaped and modified and often roads have been excavated for services. This can result in unexpected weaknesses in the ground for water to errode the earth or backfill below.
With keyhole polyurethane resin injection we can fill voids and help prevent further errosion and subsidence. we can also lift subsided road slabs after void filling.
Unstable earth and rock can be a hazard, especially on building sites. Floating rock and compacted earth can be resting on unstable clay and soil which can slide and fall, especially during rain events.
Resin injection can be used to help temporarily stabilise the earth surrounding these potential hazards to help prevent landslide or rock becomming undermined and falling.
After a tunnel is built, The permiability of rock can cause ground water to wash away earth from behind the tunnel walls and ceilings, allowing a void to form. Earth can then drop and damage the tunnel from its external.
Using void filling resin we can fill the voids behind tunnels created by ground water flow and help prevent tunnel damage from the weight of ground collapse.
Decommissioned and abandoned pipes are a hazard that can cause ground collapse as they deterorate and also lead high volumes of water to unwanted locations.
Using our void filling resin we can fill pipes without the need for removal or excavation or we can fill the voids surrounding collapsed pipes.
Resin injection can be an effective method for repairing sea walls, especially if they have cracks or other structural damage. .
Injection maintenance practices can minimise the risk of damage and ensuring the long-term stability and functionality of sea walls being damaged from the weight of ground collapse.
Mitigate the risk of subsidence on building sites using resin injection to stop landslides and subsidence which can delay construction.
Resin injection ground stabilisation before excavation can help minimise the damage that could be caused to neighbouring property.
Void filling is the process of filling voids in the earth, generally around structures, concrete or rock with polyurethane resin injection.
This resin injection is reactive and turns to a high density structural foam which can support heavy loads.
Most void filling exercises involve situations where a sense of urgency has been presented to close a void in the ground which could create financial cost or safety hazard.
Void filling is a very flexible tool which can be used in more ways than listed above.
If you have a situation where you are curious that structural foam could be used to fill voids and stabilise surrounding earth, soil or sand then get in touch and we can explore some creative solutions to your problem.
