You can disagree about my views, but I believe I can tell apart a good rubber wet pour installer in a few minutes interview with just a list of questions.

Of course, I also like to hear some market references and see some of their recent and old jobs or see how they work on a job site as a confirmation but with some of the questions at this list I think I can tell you with a big percentage of success if I am in front of a REALLY GOOD one.

Here the list of patterns and details that stand out GOOD rubber wet pour installers:
- They only use some of the best quality materials. Price of the materials is not their priority number one.
- They have selected the materials that they are using after making test samples or pilot works to know quite well their behaviour and properties.
- They experiment with new alternatives in their workshop, frequently in the off-season periods so as not to lose the opportunity to discover a product with better efficiency or other properties, but without the risk of creating a quality problem in a customer.
- They maintain the same quality materials; they know them thoroughly and they know how to use them in different situations and variations in environmental conditions.
- In their warehouse or on the construction site they keep the materials protected from environmental conditions such as rain, humidity, or extreme temperatures.
- They keep tools and machinery in the same condition that a Michelin star restaurant cook would keep their knives and pans.
- If the condition of the sub-base is not correct and is the responsibility of another contractor, they will not start the paving until the sub-base is correctly repaired.
- They will even check that the drain is working properly before starting to install the base layer.
- They will check that adequate edges are installed if it is not their responsibility or they will install an appropriate edge of those that provide reliable results.
- They will make a planning of the work site to optimise the process, establishing the place of storage, mixing, waste grouping, …
- They will protect the mixing area so as not to damage the existing pavement in a place so susceptible to staining.
- They will carefully prime the sub-base and the edges and posts of the installed play equipment or furniture to ensure a good bonding with the base and top layer.
- They have stable staff with years of experience, and they do not change staff very often.
- Each crew has a person who specialises in mixing. He is the one who makes sure of mixing proportions and times.
- They carefully record all the details on the job site: temperature and humidity of the day, batch number and reference of the materials, photos of the sub-base and all the intermediate stages of execution, incidents during the work, percentages, mixing times.
- As a result of all previous habits their warranty and repair or rework cost are negligible.


That being said, if I forgot an important factor on my list or you do not agree with any of them, do not hesitate to add a comment on the platform where you found this publication. I learn a lot from your comments and I always try to answer them as soon as possible.
