Types Of Concrete Crack Fillers

Best Concrete Crack Filler Reviews

There are 5 types of concrete crack fillers you need to be aware of to buy the best concrete patch depending on your personal occasion.

Concrete Crack Sealant

This type of concrete patch repair is meant to be used only for thin cracks and holes, up to a half-inch. The thing you need to be aware of here is that it’s only suitable for horizontal surfaces. Otherwise, it won’t create a steady and robust repair.

Concrete Repair Caulk

This one is typically applied using a caulk gun. It’s suitable for narrower cracks up to a half-inch. The advantage here is that it can be used for both vertical and horizontal holes.

Quick-Setting Cement

Further down the line, we stumble on a quick-setting concrete crack filler which is primarily used for cracks from a half-inch up to 1 inch.

In odd cases, the quick-setting cement has to be mixed with a bonding liquid to slow down the curing process so the filler can have enough time to strengthen the concrete slabs.

Hydraulic Cement

As the name suggests, this type of crack filler is mainly utilised upon cracks that feature leaks.

Patching Compound

Usually, patching compounds are primarily used upon shoal cracks. They are available in both pre-mix and dry cement powder. On the whole, they add incredible strength and durability to the slab.

Things To Consider Before Buying The Best Concrete Crack Filler

Crack Width

The first and foremost is the crack breadth. You need to be highly aware of the size of the hole you are trying to repair.

Skipping that will result in buying a crack filler which isn’t suitable for your situation. Therefore you’ll have to spend more money on the proper crack patch.

Curing Time

You need to look for a balanced time here. Too fast, or slow will harm the robustness of the concrete slab. Depending on formulation and usage, you’ll have several options to choose from.

Easy To Use

This is a crucial feature that adds incredibly to the buying decision. If you buy a sophisticated concrete crack filler that you aren’t familiar with, you’ll have trouble using it. Strive for pre-mixed crack fillers.

Temperature Tolerance

We are all familiar with the contractions and extensions that happen to any material due to hot and cold weather.

That’s why make sure the concrete crack filler is flexible enough to sustain any contractions or extensions caused by unfavourable weather.
