The construction sector is provided an array of waterproofing systems for designers and/or installers to choose from in order to achieve project requirements. However, the choice can be limited if an individual lacks the pre-requisite knowledge on their strengths and limitations. Proper design and inspection of the waterproofing systems are therefore vital to ensure waterproofing quality, and it dictates the ultimate quality of waterproofing services. The quality of the services, therefore, depends on proper design criteria and artistry activities adhering to the standard guidelines. Under performing waterproofing is often costly for an asset owner; therefore, construction stakeholders must have should endeavour to implement quality improvement techniques to offset such a situation in the future. Methods for improving the quality of waterproofing vary depending on the stage of installation and the materials available to achieve the service. Here are 5 effective ways of improving waterproofing quality.
1. Design Documentation
These documents should be developed by professional with an in-depth knowledge of waterproofing products inherent strengths and limitations. The materials selection process should ensure that the best quality products are available with awareness on all environmental conditions known to the experts. Conformity to applicable standards is a requirement to quality since the design process is always aware of the diverse parameters. The documentation would also require a quality control regime to with the intention of ensuring conformity to the design. The documentation will incorporate inspection protocols that will ensure that the objectives stipulated in the document are met.
Installation works should be performed by licensed professional suitably trained with the specific materials stipulated in the design documentation. Field verification of the design is fundamental to confirm that the workmanship conforms to the initial design criterion. As a developer, you should ensure that part-time or approximate percentage inspection is adhered to for systematic monitoring of the ongoing works. The timing of the inspection should be such that it is before installation of topping, over burden, backfill or concrete pour as this will allow repair, replacement, or correction of components that are non-conforming or damaged. The firm in charge of quality control inspection should be reputable with significant knowledge in the field to ensure quality control inspections are undertaken effectively.
Warranty is a guarantee that there will be a repair to the defective system once it becomes defective within a specified time. Waterproofing materials with warranty are most likely to conform to quality, as the manufacturer would not want to incur the extra costs related to maintenance. However, it is important to acknowledge that incorrect installation of a product will likely void the warranty being offered. A proactive waterproofing quality control program should focus on the common installation issues that lead to unwarranted waterproofing installations.
4. Pre-Construction Meeting
This meeting prior to waterproofing would focus on sequencing, techniques of construction, materials for waterproofing, and design criterion. It also assures warranty eligibility for the project as it entails the quality assurance plans. In the meeting, the representatives from the manufacturing firm focus on the guidelines for installation, criteria for reporting, relevant corrective actions for non-conformance, and the conditions acceptable for the substrate. In the same regard, there will be an opportunity for assessment and review of the sequencing and interface between trades, which improves clarity and increases the ultimate success of construction.
The should contain information on all the aspects related to the activities, including all the deficiencies, which, according to the inspector, could potentially compromise the integrity of the waterproofing system. The report includes photos of the installation, inspection date and time, weather conditions, name of the inspector, and non-conformity actions. Action may include rework or repair so that the non-conforming section finds a lasting solution. The report illustrates the shortcomings and achievements of the installation process, which one can employ to inform future works or the best systems for waterproofing.
These techniques can work to improve the quality but are limited to the knowledge that one has in informing his or her choices. Choosing the best materials or inspection firm may be difficult if you do not have sufficient information on the market and trends that inform current materials. At Waterproofing Integrity, we recognise that every project is unique and we work together with our clients to develop a quality control regime targeting their specific needs.
