Is it normal for a new build's patio slab to crack within the first year? Around Allen, it's common enough that we see it constantly. Most slab cracks here trace back to the same cause: clay soil settling underneath, not a defect in the concrete itself.
Allen Concrete Lifting checks whether the slab is still settling before sealing a crack. If it is, we level the slab first. Sealing over an active void just means the crack comes back.

FAQs
Concrete Crack Repair FAQs
Is it normal for a new build's patio slab to crack within the first year?
Especially in growing areas like Allen and Lucas where fresh clay soil is still compacting under a new pour. It's common, and it's fixable without a full replacement.
Can concrete lifting fix a trip hazard on my walkway before someone gets hurt?
When a crack comes with a height offset, lifting the low side flush removes the trip risk along with sealing the crack itself.
Why does store-bought crack filler fail sometimes?
If the slab is still settling underneath, the void keeps growing and the filler just cracks along with the concrete. Addressing the void first gives the seal a stable base.
How long does crack repair take?
Most crack repairs, with or without a lift, finish in a single visit.
Do I need a permit for crack repair?
Standard cosmetic or settling-related crack repair on an existing slab typically doesn't need one.
