Polyurethane Foam Concrete Lifting Diy

However the savings may be even greater since when concrete raising the costs of demolition removal and landscaping are eliminated.

Polyurethane foam concrete lifting diy.

Over time it is not uncommon for concrete slabs to sink or settle especially if poured over an unstable base. Drill 2 inch holes into the sunken concrete and pour a mixture of fly ash sand water and cement into the holes with a pump that produces 50 to 100 pounds of pressure. Geolift works in three steps. In this scenario you will have created a bridge of foam lifting multiple slabs.

Time and money is lost. We suggest using an air purged gun to deliver foam under the slab. Hiring a professional service to lift or jack up the slab can be costly. You can avoid this expense if you do it yourself with the help of a jacking pump which can raise the concrete slab to the needed level.

The first step is to drill holes in the problem concrete. Lifting foam will fully expand within 10 15 seconds allowing you to monitor the raising and preventing over raising the slab. Whether the dirt below it has gotten wet or the concrete was damaged accidentally you can repair either issue with foam. Lifting a sunken slab may be necessary to level the surface.

And yes it is a foam just like your beloved spray foam. The concrete lifting process general procedure followed by professionals. Foam jacking is a concrete slab repair method that uses a high density polyurethane foam to raise the slab. Ideal for heavy lifting the reaction time is designed to mimic.

This process is much the same as mud jacking an older method that uses a concrete slurry mixture to obtain the same results. Geolift works for driveways sidewalks patios garage floors even pool decks. Someone more skilled can use this method. Concrete foam jacking or concrete leveling or poly jacking when a concrete slab starts to dip inwards it s likely due to a lack of support underneath.

Polyurethane foam concrete lifting and stabilization avoid costly tear out and disruptive replacement of the slab. Once this occurs the only way to regain control over the slab is to cut through the layer of foam and attempt another lift again. Raising concrete with polyurethane foam is done with incremental injections. Polyurethane concrete raising foam needs to lift concrete but should not adhere to it.

Geolift can help to lift existing concrete surfaces and fix those problem areas around your house with much less labor.
