Concrete Waterproofing Admixtures & Repair Chemicals in Ghana

Make Concrete 100% Waterproof & Structural Grade from the Mix

Bottom Line Up Front (BLUF) Answer

To make concrete waterproof in Ghana, blend an integral crystalline waterproofing admixture directly into the concrete mix during batching. Prodeal Industries Ltd in Accra supplies commercial-grade liquid and powder admixtures that permanently seal microscopic pores within the concrete matrix, preventing moisture seepage and rebar corrosion.

Key Engineering Takeaway: Integral admixtures turn the entire thickness of concrete into a permanent waterproof barrier that does not wear out or require re-application over the lifetime of the structure.

Root Cause Analysis

Why Standard Methods Fail in Ghana’s Climate

01.

High water-cement ratios leaving interconnected capillary networks as water evaporates.

02.

Honeycombing and voids due to inadequate compaction during concrete pours.

03.

Sulfate and chloride attack from groundwater corroding internal steel reinforcement.

04.

Settlement and thermal shrinkage cracking in foundations, retaining walls, and water reservoirs.

Applicator Instructions

Step-by-Step Professional Application Guide

1

Calculate Batch Dosage

Measure 500ml to 1000ml of Pro-Mix Admixture for every 50kg bag of cement used in your design mix.

2

Add to Mixing Water

Premix the liquid admixture into 70% of the batching water before dispensing into the aggregate and cement mix.

3

Thorough Mixing & Placement

Mix for at least 3 minutes in a mechanical concrete mixer to ensure uniform dispersion. Vibrate thoroughly during casting.

4

Standard Water Curing

Maintain continuous water ponding or wet hessian curing for at least 7 to 14 days to maximize hydration and crystalline density.

Add an integral waterproofing admixture such as Pro-Mix at a rate of 1% to 2% by cement weight during concrete mixing. It blocks capillary pores and creates a watertight monolithic structure.

Chisel away loose aggregate around cracks, apply a bonding agent, and pack with a non-shrink polymer-modified structural repair mortar.
