Different surfaces, different methods
Forklift and pallet-truck routes
Main aisles and cross routes carry the most wheel movements and the joints on them break down first. Semi-rigid fillers are widely used on these routes to hold the edges up.
Construction joints
Day joints on busy routes are prone to edge damage. Movement and traffic are both checked before we decide what goes in.
Your questions answered
Can you work at a site such as Horizon Technology Park, by Rush Green?
Yes. Estates, retail parks and business parks around Rush Green, Horizon Technology Park among them, are all within reach. To start, just give us a call on 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.
Is Rush Green too far out for you?
Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.
Do you have public liability insurance?
Yes. Mastic Doctor is fully insured, public liability included.
How do you choose the sealant?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Can weather delay the job?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.
How long before trucks can use the joints?
Cure times vary with the product and how cold the slab is. You’ll get a reopening time for each area when we agree the phasing.
Can the warehouse stay open while you work?
The work is phased. We work aisle by aisle or zone by zone so the rest of the floor stays in use around the site hours and access windows you give us.
From enquiry to sign-off
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. Jobs in and around smaller places like Rush Green are typically planned as a single visit, so we ask for photographs and rough sizes first. That way the right products come on the day.
- Each area is assessed for joint width, arris damage and the wheels that cross it.
- You get a fixed quote with the product and the phasing set out.
- We remove failed material and packed debris until sound concrete is exposed on both faces.
- Dust is sucked out of the joint and a primer used if the product data sheet asks for one.
- The chosen product is placed to its specified depth and trimmed level with the floor.
- Each phase reopens when the product is ready for wheels, then we start the next.
What we need from you
- Send any specification or drawings in advance
- Let us know about inductions and permits
- Tell us your opening times and when work is allowed

Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To start the process, call the office on 01277 525 020 or email drawings and photos.

What else we do in Rush Green
Why deal with it now?
Painting or coating straight over joints rarely lasts. The joints have to be filled or sealed as joints, whether or not the floor is coated. For buildings around smaller places like Rush Green, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.
Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Doing it in-house
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
Where floor joints take the most wear near Rush Green
Rush Green is about 28 miles from central London. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital; their floors carry heavy traffic every shift. Rush Green sits in one of the drier corners of the country, the South East. Outside joints in yards and car parks still have to be dry before sealing, while winter salting gets into any joint left open.
For buildings at a park such as Horizon Technology Park, which lies east of Rush Green, brick and panel movement joints are easy to forget until one leaks. Hospital campuses such as Lister Hospital (to the north-east of Rush Green) grow in stages, leaving movement joints wherever new blocks meet old. Across sites such as Arlington Business Park, 1.7 miles to the east of Rush Green, floor and movement joints can be sealed in phases so units keep working.

Rush Green sits inside our coverage and the rest of Hertfordshire, with the same fixed quotes and 12-month guarantee as everywhere else. Rush Green is one of 371 places we cover in Hertfordshire.

Aftercare for building managers
After handover, these steps help:
- Tell us about strong cleaning chemicals before we quote
- Keep trucks off new joints until we say they’re ready
- Photograph any joint that starts to chip
- Make joint checks part of your floor inspections
Young concrete carries on shrinking, so some fillers part slightly from one face. It is a known trait of new floors and a later top-up deals with it in the majority of cases.
A broken joint on a main route is crossed by every truck on that route. Early treatment protects wheels, loads and drivers as much as the floor.
