Floor Levelling and Self Levelling Screed in Horsham

Before LVT, vinyl, large tiles or engineered wood go down in Horsham, we pour self levelling compound so they lie flat. Post-war building accounts for 30% of the town's homes, put up between 1945 and 1972, and the 1950s Needles estate and other post-war homes may need concrete floors repaired or levelled before new flooring goes down. Shop and office refits in the town centre need the same work on a commercial programme.

Needles and post-war Horsham floors before new flooring

The Needles estate went up around 1955, and post-war homes like these may need concrete floors repaired or levelled before new flooring goes down. A ground floor of that age can carry old adhesive, small cracks, patches and dips near walls. That is fine under carpet and thick underlay, which hide a lot. Put LVT or big tiles on top and each bump comes through.

Self levelling compound fixes the surface rather than the structure. We pour it onto a base that has been cleaned and primed, normally between about 2mm and 10mm thick, though a few products can go thicker. The finish is then checked with a 2m straightedge against BS 8204, where a gap of 3mm is the limit for SR1, 5mm for SR2 and 10mm for SR3. Thin sheet flooring often needs the SR1 class.

If the floor is cracked or broken, it needs mending before compound goes on. We handle that first through repairs to the concrete floor. A Needles estate floor that is well off level or coming loose needs more than compound, because pouring it thick over a floor due a screed tends to crack and lift. In that case we price a new screed, usually sand and cement for a post-war floor.

The same applies where a newer extension meets an older floor, which is a familiar problem once a post-war house has been extended at the back. A few millimetres of step across the join can be feathered out with compound so the finish runs through in one piece.

Shop and office refits in central Horsham

Swan Walk and The Forum are Horsham's central shopping areas, and RSA Insurance Group has its registered office at St Mark's Court. Broadbridge Heath has industrial parks and the RSPCA headquarters. When a unit or office is refitted, the floor beneath the old finish is rarely flat enough for new vinyl, LVT or carpet tiles.

Preparation decides whether compound stays down. Old adhesive and weak surface layers come off first. The primer has to suit the base: concrete and sand and cement screed take one type, calcium sulphate screed needs a compatible primer after the laitance is sanded off, and non-absorbent surfaces need another. Fast drying compounds keep refits moving, so flooring can follow quickly. A shop with a fixed opening date needs that certainty, so we agree the sequence of stripping, repair, priming and levelling with the shopfitter before starting.

We do not sand timber floors, and our compound is not sold for DIY use. If a shop floor needs only a few millimetres building up, a thin latex screed layer may suit. About 12 miles away, see our Dorking floor levelling page.

FAQs

Floor Levelling in Horsham: your questions

Can levelling compound go over an old concrete floor?

Usually, if the concrete is sound. It needs to be clean, free of loose material and old adhesive, and primed for the base. Cracks and broken areas should be repaired first. On a post-war Horsham floor, a thin coat of compound often brings the surface up to the flatness that LVT and tiles need.

What does SR1 flatness mean for a new floor finish?

SR1 is the tightest surface regularity class under BS 8204, allowing no more than 3mm deviation under a 2m straightedge. The looser classes are SR2 at 5mm and SR3 at 10mm. Vinyl, LVT and other thin sheet floors often specify SR1, and big tiles want a flat base too. On most Horsham floors, a coat of levelling compound is how we get there.

When does a Horsham floor need a new screed instead of levelling?

When it is broken up, hollow, loose or out of level by more than compound should take, usually beyond about 10mm. Pouring compound thick over a floor that is already failing tends to crack and come away. In those cases, repairs or a new screed come first, then a thin levelling coat if the finish needs it.
