Waterproofing Made SIMPL |

Waterproofing Made SIMPL is your clear, step-by-step guide to understanding how waterproofing systems work — and how to protect bathrooms, balconies, rooftops, and external areas from leaks, mould, and structural damage.

This SIMPL Series book gives you everything you need to know in clean, easy language without the overcomplicated jargon.

Inside you’ll learn:

• Waterproofing basics & how water actually moves through buildings

Gravity, capillary action, vapour pressure, lateral movement — and why even tiny gaps cause big problems.

• Membranes, primers, tapes & sealants made SIMPL

Liquid membranes, sheet systems, cementitious coatings, bond breakers, reinforcement tapes, waterproof boards, primers — what to use and where.

• Surface preparation

Substrate stability, moisture testing, crack repair, priming, falls, cleaning, and the full pre-membrane checklist.

• Bathrooms & internal wet areas

Showers, niches, wastes, baths, hobs, transitions, splash zones, toilet areas — and the correct membrane heights for compliance.

• Balconies & external areas

Falls, drainage, balcony edges, door thresholds, penetrations, screeds, flashing, external membranes, movement joints, and wind-driven rain control.

• Rooftops & large flat surfaces

Sheet membranes, parapet walls, pond testing, scuppers, overflows, skylights, heavy-duty detailing, protection layers, and long-term durability.

• Bond breakers, corners & junctions

Internal and external corners, movement zones, penetrations, drains, transitions, hob details — and how to reinforce them properly.

• Waterproofing around penetrations

Pipes, mixers, drains, balcony posts, balustrade fixings, rooftop penetrations, planter boxes, and podium detailing.

• Common waterproofing mistakes & failures

Why membranes peel, crack, blister, leak, and fail — plus every preventable installer mistake.

• DIY awareness & homeowner checks

What homeowners can safely inspect, what they must never touch, early signs of failure, mould indicators, and when to call a licensed professional.

Whether you're learning waterproofing, auditing your own trades, or educating customers, this book gives you the SIMPL foundations to understand waterproofing the right way — and prevent leaks before they happen.

Waterproofing done right is invisible — until the day it fails.
This book ensures it doesn’t.
