Materials in Short Supply, Demand at 318%: What Changed for Waterproofers in March 2026

Demand Has Exploded, But Materials Haven't Kept Up

Demand for waterproofing and roof repair services grew by 318% in February 2026 compared to January, according to data from the Fixando platform. This figure is more than just a market indicator: it signals that there are jobs that need doing now, clients willing to pay, and at the same time, growing pressure on everything that goes into your supplier's order.

The problem is that supply has not kept pace. Forty-four per cent of service requests went unanswered — not for lack of willingness on the part of professionals, but because labour, materials and time simply aren't enough to go around. When demand grows at this rate, suppliers gain the power to dictate terms: longer delivery times, limited stock and rising prices.

For those working with membranes, bituminous sheets or waterproofing coatings, this has an immediate practical consequence: the price you used to calculate last week's quote may no longer be the price you'll pay when the time comes to purchase the material. The window between quoting and executing has never been as risky as it is now.

37% of Specialists Report Waterproofing Material Shortages

In a survey conducted by Fixando among 2,763 specialists, 37% reported difficulties obtaining waterproofing materials within their usual lead times. This figure is directly linked to the delays that 77% of professionals say they are experiencing on jobs. When materials are delayed, work is delayed. When work is delayed, the client becomes dissatisfied. And when the client is dissatisfied with timelines the professional cannot control, it is the waterproofer who ends up looking bad.

The shortage does not affect all products equally. Polymeric bituminous membranes, EPDM membranes and solvent-based primers are the materials currently under the greatest stock pressure, precisely because they are the most widely used in urgent roof repairs following heavy rainfall. If your usual supplier is out of stock, the nearest alternative may already be 20 to 30% more expensive simply due to localised shortage effects.

The practical recommendation is straightforward: before closing any quote right now, confirm real material availability with your supplier — not the theoretical availability shown in the online catalogue. A quote accepted on the basis of a price you cannot guarantee is worse than not winning the job at all.

Bianplast Raises Prices by 10% from 15 March: What to Do with Pending Quotes

Bianplast has confirmed a 10% price adjustment effective 15 March 2026. For any waterproofer using this brand's products who has submitted quotes before that date, the arithmetic is straightforward: if the work only starts in April, materials will cost 10% more than the figure used to calculate your margin.

A concrete example: on a job with £800 worth of Bianplast materials, that adjustment means £80 less in your margin. On larger jobs, with £3,000 or £4,000 worth of material, we are talking about £300 to £400 coming out of your pocket if you don't act before the 15th. If you have the capacity to bring forward stock purchases for already confirmed jobs, this week is the last window to do so at the current price.

For pending quotes that have not yet been accepted by the client, there is a decision to make now: resubmit the quote updated with the new material price, or include an explicit clause stating that material prices are subject to revision if the job does not start by a specific date. Leaving the old quote outstanding with no note whatsoever is the highest-risk option.

How to Protect Your Margins When the Market Won't Stop Shifting

The waterproofing market in March 2026 is presenting a genuine opportunity: service prices have risen 26% and demand outstrips supply. But the trap lies in locking in fixed-price contracts when material costs keep moving. The most basic protection is a price revision clause in every quote — especially those valid for more than two weeks or where work is scheduled to start after 15 March.

If you are still calculating quotes manually or managing versions in spreadsheets, this is exactly the kind of market that makes that process dangerous. When a supplier updates prices or confirms a shortage, you need to be able to revise and resubmit proposals on the same day. Tools like Prummo (prummo.app) allow you to update material prices across active quotes without having to rewrite everything from scratch — which right now can make the difference between absorbing a loss or passing the real cost on to the client in time.
