The dead load of NWC limits span length and increases substructure requirements, all of which work against the goals of building long-lasting and efficient infrastructure. Reports by Virginia Transportation Research Council (VTRC) suggest that effective control of early-age cracking can help limit later-age cracking.
Concrete cracks can be nerve-wracking to deal with, impacting not only the aesthetics, but also the structural integrity of a building. Control measures are needed to prevent differential volume changes in the concrete. By equally distributing micro fibers throughout the concrete, you can improve impact resistance and crack control.
If you’re pouring a foundation, ensure the location meets local building codes. Build a Formwork Create a sturdy wooden frame to contain the concrete. Allow for Proper CuringCuring is the process of allowing the concrete to harden and reach its maximum strength. Level the ground using a shovel, rake, and tamper.
The project leveraged four alternative delivery methods including: landside and airside construction management at-risk, a design-build-operate-maintain baggage team, design-bid-build award contracts and multiple design-build concession/tenant packages.

Now, it has been converted into a new eight-story commercial office building. However, given the building’s proximity to the London Underground and HS2, vibration control was required for the newly excavated basement level. A lot goes on in the redevelopment of prestigious buildings like Norfolk House.
The installation process involves thorough preparation (diamond grinding, cleaning and moisture barrier application), followed by professional epoxy application and a proper curing period of 5-7 days for optimal results. Curing Time Epoxy flooring requires adequate curing time to reach its full potential. to 3 per square foot.
As buildings soar higher and higher, it’s fascinating to see new technologies emerging to meet this demand. Here are three trends to keep an eye on if you’re designing or planning a new high rise building. The core and perimeter steel can be built at the same time, because there’s no need to wait for the concrete to cure.
This means that polyurea systems cure faster, which can help contractors complete their work faster. Polyurethane/polyurea hybrids and polyurethane systems require catalysts to control the reaction.

To illustrate the importance of moisture and pH testing in successful installations and demonstrate why building professionals should require installers to be certified, here is a look at what can happen when these factors are left out of the equation. Some installation issues relate to buckling, crowning, and cupping.
With rising material costs, environmental concerns, and increasing regulations, contractors and developers are searching for ways to build cost-effective yet durable structures. These materials come from demolished buildings and are repurposed for new construction, reducing waste and cutting material costs.
Image/Coates From maintaining thermal comfort and personal safety, to enabling manufacturing, building and industrial processes, many businesses rely on temperature-controlled environments. Temporary event spaces often require heating solutions too, particularly in marquees or halls that aren’t geared for climate control.
Commercial applications benefit from epoxy’s ability to withstand heavy machinery and frequent traffic, particularly in Portsmouth’s warehouses, industrial estates, retail outlets and office buildings. Office buildings throughout Portsmouth increasingly choose epoxy resin floors for their combination of elegance and functionality.
Building on straightforward material testing and proven project successes, the industry is making significant strides toward developing accountable language and precise definitions that can be universally specified to address concrete floor challenges.

For example, control flow concrete is ideal for most slab on grade and formed concrete applications, while self-consolidating concrete is advantageous for use in highly reinforced and very difficult to cast applications … more. Delivering, handling, placing, finishing and curing concrete can be difficult during the hot summer months.
Although waterproofing systems account for a small fraction of the cost of an overall building project, if the wrong solution is chosen or it’s installed improperly, the costs of remediation can be tremendous. . This helps to reduce potential health risks for building inhabitants. Risk of water ingress. Product Applications.

To prevent shrinkage, one must have excellent control of early setting the mass concrete intended for a large structure. In mass concrete, to obtain a durable structure with more economy, the mass concrete should be properly designed, placed, and cured. The temperature shrinkage is the major problem in mass concrete work.

In an SSG application, the silicone sealant bonding the unit to the framing is typically a high-performance, multi-component adhesive designed to function as the structural attachment between noted components, specifically formulated for its adhesive and curing properties which also serves as a primary seal against air and water infiltration.
Water infiltration can cause problems by corroding the structure and damaging materials housed within the building. Contaminants in the soil and groundwater can pose threats to indoor air quality as vapors from the soil migrate into buildings constructed on these sites. Building Envelope Solutions. Soil contamination.
Some of these products claim to have moisture control properties, so it’s like getting two products—flooring adhesive and moisture barrier—in one.
