About our expansion joint sealing in Strathmartine
Our movement joint work takes in walls, panels, decks and floors: vertical joints in brick and block facades, joints between precast or cladding panels, concrete slab and deck joints, ramps, podiums and internal floors. Every one calls for a sealant picked for its movement, exposure and traffic. We work on car park decks and ramps, precast concrete panel joints and podiums and floor movement joints, and what we are called in for most is layers of sealant in a movement joint and damp inside where a wall movement joint has failed. Facilities teams, main contractors and managing agents in Strathmartine tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
Around smaller Scottish places like Strathmartine, slabs needing attention are often in agricultural buildings, workshops, schools and hotels. Concrete slabs and yards there take vehicles and weather.
Work we carry out comes with a 12-month guarantee. Should something we installed fail, phone 01277 525 020 or use the quote form and we’ll come back to it.

What the job involves on each surface
Concrete and precast panel joints
Precast panels often have surface residues that sealant won’t bond to. We prepare the faces thoroughly and prime where the maker calls for it and check the edges for soundness as we go.
Joints between different materials
Junctions between brick and render, or concrete and cladding, move independently. We choose a sealant that grips both faces.
Keeping the joints sound
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Leave barriers in place until fresh joint sealant has cured
- Look over external and deck joints after a hard winter
- Brief car park operatives to protect joint lines during winter clearance
- Avoid parking heavy plant or pallets on joint lines
Every joint we seal is backed by a 12-month guarantee on workmanship. Record which product went into which joints in the building file, so the next reseal starts with the facts.
On a multi-storey car park, a failed joint usually shows up as a leak onto the deck underneath. Salty water dripping through stains soffits and lands on parked vehicles and it can affect the structure over time. Sealing the joint promptly stops it at source.

Honest limits
Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be one of these:
- Crumbling edges that would give a new bead nothing sound to grip
- Proprietary pre-formed expansion joint systems
- Movement on a scale no sealant is meant to absorb
If in doubt, speak to us on 01277 525 020 or email us and we will say what we think before you book.

Diagnose, treat, sign off
Site rules come first: signing in, inductions and any permit to work. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. Where we can, we combine work around Strathmartine with other jobs nearby. Let us know if your dates have any give.
- We start with photographs, approximate lengths and any drawings, visiting where needed.
- We compare each joint’s width with the movement and the sealant’s capability.
- Every joint is cleared of the failed seal and any grit packed into it.
- Any broken arrises or friable edges are flagged before work goes further.
- A sealant suited to the movement and traffic is laid to depth and tooled.
- Each area is handed back after its cure time, under our 12-month guarantee.
Before we start on site
- Send any specification or drawings in advance
- Move anything stored against the joints
- Tell us which areas need to stay in use

Warehouse floors and decks around Strathmartine
Strathmartine has at least three named business or industrial parks inside a 3-mile radius. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest. Being in the east of Scotland, Strathmartine gets less rain than the west coast. Frost and de-icing salt still find their way into open external joints. Autumn is a sensible time to seal them.
Campuses like Abertay University (to the south of Strathmartine) mix old and new buildings, with movement joints wherever they meet. Sites like Kings Cross Hospital (to the south of Strathmartine) carry ambulances, deliveries and visitors’ cars over their road and deck joints.

FAQs: Strathmartine
Is Strathmartine too far out for you?
Not at all: smaller places are covered as well as towns. We work across every Scottish council area. We plan jobs in smaller places so return trips are kept to a minimum.
Would you work within a site like Kings Cross Hospital?
Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Are you CHAS accredited and on Constructionline?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
Is it fine to apply new sealant on top of old?
No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
How long will the new sealant last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
Can weather delay the job?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
Can you work while the building is occupied?
Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.
