Industry: Residential

Type of work: Concrete Cancer Remediation

The undertaken actions at 1 Riverpark Drive, Liverpool, involved comprehensive concrete repair measures spanning a total of 121 meters long and 1.2 meters wide with a focus on 10 individual unit blocks. The repair scope included addressing architectural concrete sections on level 1, specifically targeting balcony areas.

Primary issues

The primary concerns addressed revolve around the need for concrete cancer repair, focusing on contaminated areas, loose concrete, rust on steel reinforcement, and potential water damage to balcony slabs.

Root causes of these issues

These issues likely stem from natural wear and tear, exposure to environmental elements, and, in some cases, builder-related construction causing degradation. The balcony slab edges may be susceptible to water damage, necessitating protective measures.

Solutions we implemented

To mitigate these concerns, actions include cleaning and removing loose concrete and builder-induced rubbish, removal of rust on steel reinforcement, application of Nitoprime zinc-rich anti-corrosion primer, cleaning scabbled concrete surfaces, priming small repairs with HB 40 repair product, conducting major repairs on larger areas, applying cement bedding, rendering balcony slab edges, and membraning larger surfaces with two coats of waterproofing membrane for future water damage protection.

Outcomes

Following these interventions, observed outcomes include enhanced structural integrity, improved aesthetic appearance, and fortified resistance against potential water damage to concrete areas and balcony slabs in the future.

Industry: Residential

Type of work: Roof Repair

The project involved a comprehensive approach to roof and gutter system replacement for a leaking roof, ensuring structural integrity, compliance with safety standards, and effective stormwater management. The utilization of existing infrastructure, careful material handling, and adherence to specifications contributed to the successful completion of the project.

Primary issues

The project’s primary challenges to replace the damaged roof included delays or complications in obtaining rooftop certification for anchor points, risks of damage to Kliplok roof sheeting during removal and storage, and challenges in achieving required falls in the box gutter. The placement of new sump outlets and the matching of the existing parapet capping profile posed challenges as well. Logistics for waste disposal, coordination with residents to minimize disruptions, compliance and certification delays, and potential safety risks during height-related tasks were additional issues that had to be dealt with during the project. Adaptability, meticulous planning, and proactive risk management were crucial for navigating these issues and ensuring project success.

Root causes of these issues

The potential root causes of a leaking Kliplok metal roof include loose or damaged fasteners, incorrect installations, faulty flashings or sealants, cracked or damaged Kliplok sheets, ponding water due to improper slope or drainage, flashing issues around penetrations, clogged or damaged box gutters hindering proper drainage, poor roof design or installation practices, aging and wear of roofing materials and the lack of routine maintenance. Addressing these issues requires a comprehensive roof inspection, precise identification of the root cause, and appropriate remedial actions to ensure the roof’s integrity and prevent further leaks.

Solutions we implemented

To address the leaking Kliplok metal roof during renovation we tightened and/or replacing loose and damaged fasteners, corrected lap joint installations with proper overlap and sealants, replacing faulty capping and flashing and sealants with weather-resistant alternatives, improved roof slope and drainage to eliminate ponding water, upgrading flashings around penetrations, addressed design flaws and original installation errors and recommended implementing a routine maintenance schedule be carried out on a semi-annual basis.

Outcomes

Renovating this Kliplok metal deck roof yielded a range of positive outcomes. These include an enhanced watertight roof, strengthened structural integrity, improved drainage systems, upgraded flashings and seals, and the application of high-quality materials and coatings for increased durability and resistance to weathering. The aesthetic appeal is heightened, and compliance with regulations ensures safety and performance standards are met. The renovation contributes to extended roof lifespan and heightened resilience to adverse weather conditions.
