What is the difference between concrete sealer and Waterproofer?

One of the differences between a concrete sealer and a concrete waterproofer (sometimes called penetrating sealer) is that a sealer will form a protective layer over the surface while a waterproofer will penetrate down into the pours of the concrete and the protective layer will form there.

How strong is Type S mortar?

Type S Mortar Mix Offering a high compressive strength of over 1,800 psi and a high-tensile bond strength, type S mortar is suitable for many projects at or below grade. It performs extremely well to withstand soil pressure and wind and seismic loads.

How do you make strong concrete mix?

In general, the aggregate component of a concrete or mortar mix is usually several times that of the cement.
